catena-Poly[[[pyridinecopper(II)]-(μ-2-oxidonaphthalene-1-carbaldehyde picolinoylhydrazonato)-[pyridinecopper(II)]-μ-sulfato] diethyl ether hemisolvate]
The title compound, {[Cu2(C17H11N3O)(SO4)(C5H5N)2]·0.5C4H10O}n, was synthesized by the reaction of 2-hydroxy-1-naphthylaldehyde-2-pyridinecarboxylhydrazone with copper sulfonate. A one-dimensional polymer was obtained via self-assembly. Each Cu ion is located in a distorted square-pyramidal coordination environment, with one Cu ion coordinated by two N and three O atoms, while the other links to two O and three N atoms. In the crystal, weak intermolecular C—H⋯O interactions connect the chains into a two-dimensional network
catena-Poly[[[μ-cyanido-1:2κ2 C:N-tricyanido-1κ3 C-bis(ethylenediamine)-2κ4 N,N′-copper(II)iron(II)]-μ-cyanido-κ2 C:N-[bis(ethylenediamine-κ2 N,N′)copper(II)]-μ-cyanido-κ2 N:C] 4.5-hydrate]
The asymmetric unit of the title compound, {[Cu2Fe(CN)6(C2H8N2)4]·4.5H2O}n, consists of two [Cu(C2H8N2)2]2+ cations, one [Fe(CN)6]4− anion, four water molecules and a half water molecule that lies on a twofold rotation axis. The FeII atom is coordinated by six C atoms from three terminal and three doubly bridging CN− ligands. The bridging CN− ligands connect the anion to a five-coordinate [Cu(C2H8N2)2]2+ cation and to two symmetry-related six-coordinate [Cu(C2H8N2)2]2+ cations, forming a one-dimensional polymer in the ab plane. Intermolecular hydrogen bonds connect the polymer units into a three-dimensional network
Bis(μ-chloroacetato-κ2 O:O′)bis(chloroacetato-κO)di-μ3-oxido-tetrakis[dibenzyltin(IV)]
The title tetranuclear complex molecule, [Sn4(C7H7)8(C2H2ClO2)4O2], has crystallographically imposed inversion symmetry. Each Sn atom has a distorted trigonal–bipyramidal geometry, with the equatorial plane formed by an oxido O atom and two C atoms of two benzyl anions. The configuration of the complex is stabilized by a pair of C—H⋯O hydrogen bonds. In the crystal, complex molecules are linked into zigzag chains along [110] by C—H⋯O hydrogen bonds
catena-Poly[[trimethyltin(IV)]-μ-quinaldato]
The title compound, [Sn(CH3)3(C10H6NO2)]n, forms an extended one-dimensional chain structure. There are two independent SnIV ions, both of which are in slightly distorted trigonal-bipyramidal coordination environments with two symmetry-related O atoms in the axial sites. In each case, the SnIV ion and one of the three equatorial C atoms lie on a crystallographic twofold axis
Di-μ-methanolato-κ4 O:O-bis[trichlorido(dimethylformamide-κO)tin(IV)]
The title compound, [Sn2(CH3O)2Cl6(C3H7NO)2], contains two hexacoordinated SnIV atoms symmetrically bridged by two deprotonated methanol ligands, with an inversion center in the middle of the planar Sn2O2 ring. The other sites of the distorted octahedral coordination geometry of the SnIV atom are occupied by three Cl atoms and one O atom from a dimethylformamide molecule. The complex molecules are connected by weak C—H⋯Cl hydrogen bonds into a two-dimensional supramolecular network parallel to (10)
3-Hydroxy-N′-[(E)-2-thienylmethylidene]-2-naphthohydrazide
The asymmetric unit of the title compound, C16H12N2O2S, contains three independent molecules. Intramolecular N—H⋯O hydrogen bonds in the three molecules lead to very similar conformations: the thiopene ring and naphthalene ring system in the three molecules form dihedral angles of 10.3 (2), 9.1 (2) and 9.3 (3)°. In the crystal structure, intermolecular O—H⋯O hydrogen bonds link the molecules into chains propagating in [031]
Dimethylbis(3-methylsulfanyl-1,2,4-thiadiazole-5-thiolato)tin(IV)
In the title compound, [Sn(CH3)2(C3H3N2S3)2], the SnIV atom is coordinated within a C2N2S2 donor set that defines a skew-trapezoidal bipyramidal geometry in which the methyl groups lie over the weakly coordinated N atoms. Two independent molecules comprise the asymmetric unit, each of which lies on a mirror plane that passes through the C2Sn unit
Bis(2-hydroxybenzaldehyde oximato-κO)triphenylantimony(V)
The molecule of the title compound, [Sb(C6H5)3(C7H6NO2)2], is located on a twofold axis defined by the metal center and two C atoms of a coordinated phenyl group. The Sb center has a slightly distorted trigonal-bipyramidal geometry, with the axial positions occupied by the O atoms of symmetry-related 2-hydroxybenzaldehyde oximate ligands. An intramolecular O—H⋯N interaction is present. The crystal structure is stabilized by C—H⋯O interactions
